MAINTENANCE WARNING TEMP. INDICATOR WARNING TEMP. Indicator flashes red and projector is automatically turned off when an internal temperature of a projector exceeds normal temperature. Wait at least 5 minutes before turning on projector again. When WARNING TEMP. Indicator continues to flash, check items listed below. Ventilation Slots of a projector may be blocked.
Page 24: Air Filter Care And Cleaning
AIR FILTER CARE AND CLEANING Air Filter prevents dust from accumulating on surface of Projection Lens and Projection Mirror. Should Air Filter become clogged with dust particles, it will reduce Cooling Fans' effectiveness and may result in internal heat build up and adversely affect life of a projector.
Page 25 Improvement of the Optical parts After long of use,dust and other particles will accumulate on the LCD panel,prism,mirror,polarized glass,lens,etc.,causing the picture to darken or color to blur. If this occurs,clean the inside of optical unit. Remove dust other particles using air spray. If dirt cannot be removed by air spray, disassemble and clean the optical unit.
